Leslie I. Szabó (not to confused with the musician of the same name) is a Hungarian businessman and inventor of free energy machines. He is CEO with Gamma Manager Ltd. in Budaörs, Hungary.
Szabó claims a power plant utilizing his technology was currently built in China, producing an excess energy of 1,000 MW drawn from space energy.
Specialist literature on the subject is not available, a reception in international journals of energy economies or from professional circles is not detectable (April 2011). Szabó just names a few witnesses who affirm the claims about the invention.
